TRUCK.

SPECIFICATION forming part of Letters Patent No. 590,436, datedSeptember 21, 1897.

Application filed arch 9, 1896. Renewed April 3, 1897- Serial No.630,629. (No model.)

To (all whom. it nut concern.-

Be it known that we, PHILIP J. MARVEL and JOSEPH H. MARVEL, citizens ofthe United States, and residents of Atlantic City, in the county ofAtlantic and State of New Jersey, have invented certain new and usefulImprovements in Trucks, of which the following is a specification.

Our invention relates to improvements in that class of trucks forhandling and transporting packages-as barrels, boxes, and the like whichare furnished with hooks or grapples adapted to assist in loading thepackage upon the truck; and the object of our invention is to furnish animproved means for attaching'the grapple to the upper end of a carryingarm or standard, the lower end of which is secured to the truck, inorder to obtain a greater swinging movement of the grapple than hasheretofore been possible.

In the accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate similar parts throughout theseveral views, Figure 1 is a perspective view of a truck furnished withour improvements; Fig. 2, a side elevation of the upper part of theswinging arm, showing the inside end of grapple-arm, disk which carriesthis arm, and pawl for engaging ratchet on said disk; Fig. 3, a plan ofFig. 2; Fig. 4, a side elevation of disk; Fig. 5, an end elevation ofFig. &; Fig. 6, a perspective view of a truck furnished with twograpples and the forward end of which is furnished with hooks which maybe thrown into or out of operative action at will; Fig. 7, a perspectiveview of the forward end of truck, showingthe hooks thrown back out ofoperative position.

A are the side rails, and B wheels upon the forward end of truck.

0 is a shoe upon the forward end of truck.

D is a rocking arm pivoted upon a rod or shaft E, which passes throughthe side rails A.

F is a tube surrounding shaft E, the ends of which bear against theinner sides of the rocking arm and prevent these sides from movingtoward one another.

G is a hook or grapple which passes through a notch II, Figs. 4 and 5,in the side of a disk I, which is'ecoentrically pivoted at J to the freeend of the rocking arm D. One side of their upper ends are just farenough apart to receive the disk I without binding upon it. The slot Hin the disk is a trifle wider than the arm of the grapple, as best shownin Fig. 2, and this arm may be moved back and forth the other againstthe other side rail, while I in this slot to permit the hook upon itsend to engage smaller or larger packages.

'When the point of the hook is in engagement with apackage which is tobe lifted upon the truck, it is necessary that either the disk I belocked and then the arm G be locked to this disk or that the arm Gitself be locked.

In Fig. 1, K is a sliding dog carried upon the swinging arm D. When thegrapple is engaged with the package to be lifted, the dog K is slid upuntil its upper end engages the under part of arm G, as shown. Thisfirmly locks this arm, preventing any longitudinal movement of the same,and also prevents any rotation of the arm or disk about the pivot J, andwhen the handles are lowered the weight of the operator is transferredto the package through the grapple and the package is lifted upon thetruck.

In Fig. 2 that part of the periphery of disk I opposite the pivot J isfurnished with teeth L, with which a pawl M, pivoted at N to theswinging arm, is adapted to'engage. When the grapple is engaged with thepackage to be lifted, the pawl IWI is engaged with one of the teeth L,and when the strain of lifting the package is thrown upon the grapplethe disk is prevented by the teeth and pawl from rotating upon the pivotJ, at the same time the arm G is locked, so that its upper end bindsagainst the upper forward end of the notch in the disk, while its lowerend binds against the lower rear end of this notch, the arm beingthereby locked to the disk.

S is a handle secured to the rear end of the grapple-arm, by means ofwhich this arm may be conveniently operated.

For very wide packages it is sometimes desirable to furnish the truckwith two grapples.

IOO

Such an arrangement is shown in Fig. (3. In this case the upper ends ofthe swinging arms are far apart and each one carries aneccentrically-pivoteddisk and grapple, the operation of which issubstantially the same as that before described.

The advantage of the eccentrically-pivoted disk arrangement is that byits use we are enabled to get a greater swinging movement of thegrapple-arm than is possible without it. In Figs. 6 and 7 the forwardend of the truck is furnished with the usual shoe 0 and in addition isfurnished with hooks P, which may be moved either in or out of operativeposition, as desired.

The ordinary shoe 0 is used when trunks or other articles that might beinjured by the hooksare to be lifted, but if a package that would not beinjured by the hooks is to be lifted the use of the hooks is preferable,for there is with them apt to be less slip. The hooks are pivotallysecured to the side rails A at R and maybe swung down so as to restagainst the shoe 0, as shown in Fig. 6, orbackward, as shown in Fig. 7,completely out of the way.

Having thus described our invention, we claimoted to the upper end ofsaid arm, a grapple carried by said disk, and meansfor preventing saiddisk from turning upon its pivot, all substantially as and for thepurposes setforth.

2. The combination with a truck, substantially as illustrated, of aswinging arm pivoted at its lower end, a disk eccentricallypivoted tothe upper end of said arm, a slot in said disk, a grapple the arm ofwhich passes through said slot, teeth upon the periphery of said disk,and a pawl pivoted to said arm adapted to engage said teeth, allsubstantially as and for the purposes set forth.

The combination with a truck substantially as illustrated of an arm orupright carried by said truck, adisk eccentrically pivoted to the upperend of said arm, a grapple carried by said disk, and means forpreventing said disk from turning upon its pivot when the grapple is inuse.
